TUBE-CLEANER.

Specification of Letters Patent.

Patented Sept. 11, 19.06,

Application led January 31, 1903. Serial No. 141.303.

To rtZZ whom it may concern:

Be-it known that I, ALFRED H. SwARrz, of

' Chicago, Cook county, Illinois, have invented ing drawings,.formingpart of this specifica-- tion, in which- Figure l is a sectional sideelevation showing a cleaner constructed in accordance with my invention,and Fig. 2 is a detail view of the cleaning-tool proper or head.

My invention relatesto that class oi.' tubecleaners wherein a cleaningtool or tools are rotated by a turbine; and the object of the inventionis to provide a simple, cheap, and compact tool this type which isadapted for small tubes and which will give a rapid and efficientcleaning action upon the scale or foreign matter on the tube.

In the drawings, 2 represents a turbinecasing in which a turbine of anysuitable form is mounted, the rotary shaft 3 of this turbine having auniversal coupling 4 with a head or plug 5. The cleaning-tool -6 has awrought iron or steel stem cast into it in casting the tool itself,which stem is screwed into the v head 5, and the tool itself consists ofa tapering blade of chilled cast-iron having beveled edge portions 8,which are preferably serrated or toothed, as shown. The points of theserrated teeth extend in the opposite direction on one side from that ofthe other, so that both of them extend in the direction of rotation, andwhen the turbine is driven the toothed head or blade will swing outunder centrifugal force, this being allowed by the universal joint, andwhile moving around in a generally circular or spiral path will delivera succession of blows upon the scale to` loosen and dislodge it.

The advantages of my invention result from the use of the universaljoint in connection with the axial taperinv blade or head.

'lhe use of this single axial blade with opposite abrading edges enablesthe device to be used in small tubes, whilethe angular teeth give arapid and efficient cutting action.

Variations maybe made in the form of the head or blade and the teethwithout departing from my invent' n.

I claim- 1'.A In a tube-cleaner, a head having flat wings projecting onopposite sides of its longitudinal axis, said Wings tapering toward thefront end and having oppositely beveled 'or inclined edges overhanvingopposite sides of an axial longitudinal pllane, anda screwstem securedby casting the head about it; substantially as described.

2. A tube-cleaner having a head comprisc 'ing an axial wedge-shapedcutter-body with j its opposite edges beveled or inclined in oppoj sitedirections to give cutting edges on opposite sides of axial planes, anda stern` embedded in the head by casting the head about it;substantially as described.

' 3. A tube-cleaner head comprising a tapered bodyof hard cast metal,and a screw:

stem of softer metal held within a thickened `portion of the head;substantially as de- 4. A tube-cleaner head of flat arrow shape` 5. Atube-cleaner head of tapered form,-

having a thickened central portion, the 'head being of cast metal withthe stem of a screw fixed in the thickened cast central portion;

substantially as described.

6.A tube-cleaner head. consisting of achilled-iron casting of eneralarrow shape with a thickened centri portion cast about the st em of aprojecting screw; substantially as described.

7. A tube-cleaner head lof general arrow shape with tapered serratededgeabeveled in opposite directions with reference'to an axialongitudinal plane to give op ositely- -projectin cutter edges, thecentra parft of the head eing thickened-and 4cast aboutlthe stem of a.projecting screwto serve asanlt taching means; substantiallyasdescribed."

8. In a tube-cleaner, a flat, tapered blade having a thickened centralportioncast about a projecting screw-stem, and a shaft'havingljuniversal-joint connection wlth said stem;

substantially as described.

9. A tube-cleaner head comprising a body of hard cast metal havingtapered or inclined IOO .edges and a threaded portion of softer metalheld Within e thickened portion of the heard and adapted to connect thehead to the 1no tor; substantially as described. A

10. A tube-cleaner head comprising a body i of cast metal having cuttingedges, and a l threaded portion of softer metal held Within the rearportion ohthe head and arranged to l seoisoe connect it to the drivingmeans; 'substantially as described,

In testimony whereof 1 have hereunto set my hand.
